Speccation of Letters Patent.

Patented July 12, 1910.

Application filed September 10, 1908. Serial No. L152,500.

To all whom it may concern:

Be it known that I, SWAN N. SWAN, a citizen of the United States of America, and resident of Freeport, Illinois, have invented a certain new and useful Improvement in Reed-Organs, of which the following is a specification.

My invention relates to improvements in organs, and has for its object the production of an organ in which the valves controlling the admission of wind are kept in place despite the rough usage to which the instruments are usually subjected.

A further object is the production of improved valve means that can be readily removed from the instrument or put in place, and that are so held, when in place, as not to be disturbed.

A further object is the utilization of an aluminum tracker pin for actuating said valves.

These and such other objects as may hereinafter appear are attained by my device, an embodiment of which is illustrated in the accompanying drawings, in which- Figure 1 represents a sectional view through a portion of an organ movement showing my device in place. Fig. 2 is a bottom plan view of Fig. 1. Fig. 3 represents a perspective view of a single valve.

Like numerals of reference indicate like parts in the several gures of the drawing.

Referring now to the drawings t represents an action frame on which is mounted the cell-board 5. This cell-board is provided With a plurality of openings closed by valves 6, held in position by means of springs 7, one end of which 8 is fastened in a block secured to the frame, the other end 9 iitting within a groove 10 in the face of the valve. Reeds 11 arelocated above the valve 9 and mutes 12 control the admission of air through the reeds into chambers formed by the partitions 11a-11a. Keys 13 are mounted on the organ frame at 15, and pins 16 are mounted on the pin frame 17 adapted to enter corresponding openings in the keys 13. Tracker-pins 18 preferably of aluminiun, pass through the mute board 19 and engage the tops of the valves 6 6 at 20. An ordinary stop 21 is shown in Fig. 1. An ordinary octave coupler 22 is actuated by a coupler butt 28 secured to the bottom of the key. Hinged plates or curtains 24 are shown covering the mute bars 12. The cell board 5 is provided with a plurality of sets of pins 25 adapted to fit within slots 26 in the opposite ends of the valve 6, thus preventing any lateral movement of the valve.

Referring now to the operation of my device, when the keys are struck the tracker pin 1S presses downwardly on the cushion 24 of the valve 6, pressing the spring 7 downwardly. This permits the admission of air to the reed provided the corresponding mute 12 is open. These valves slide downwardly on the pins 25 and are held by the pins and the spring 7 from being dislodged from their proper position. Upon releasing the key, the spring 7 forces the valve back again into closed position.

Itwill be noted that I provide along the center of the valve a longitudinal groove 10 within which the end of the spring 7 is seated. It is evident that a small depression in the face of the valve would serve the purpose of the groove provided the springs 7 were all of uniform length, but these springs often vary in length, the resiliency of the spring being regulated by changing the length, and even in the event that the same size springs are used, any slight variation in setting them in place would prevent the end 9 of the spring from registering with any small opening in the face of the valve.. By the use of the groove, however, the end of the spring is always seated within the groove, holding the valve in place and preventing the spring from lateral movement. Heretofore it has been a very common occurrence in moving organs from place to place and subjecting them to sudden jars and jolts, to have the springs slip off the valve between adjacent valves, thus causing the valve to fall open. In order to repair this, it becomes necessary to gain access to the interior of the instrument, which occasions considerable trouble and expense. This is entirely done away with by the use of my improved valve in connection with the spring, as the spring, regardless of its length or strength, is always held within the groove. At the same time, the valve is readily removable when occasion arises, making it necessary to remove it, as the spring can be pulled downwardly and twisted to one side, without in any way injuring the spring.

I also nd that by the use of the old form of tracker pin made from wood the changes in the atmosphere and temperature often grooves, said valves controlling said reeds, said grooves extending through the entire 15 length of the outer faces of said valves, and springs for holding said valves normally in closed position, one end of each of said springs fitting Within one of said grooves.

Signed by me at Freeport, Illinois, this 20 5th day of Sept., 1908.
